What is it? Spherical HTML2O3 Powder ? Aluminium oxide can be described as an inorganic compound with the chemical formula Al2O3. It is a high-hardness compound that has a melting temperature of 2054 degC and boiling point of 2980 degC. It is an ionized crystalline that can be easily ionized at high temperatures. This crystal is commonly used in the production of refractory materials.
Industrial alumina is made from bauxite, Al2O3*3H2O and diaspore. Chemical methods are used to prepare Al2O3 with high purity requirements. There are many Al2O3 isomorphous crystals. More then 10 types are known. There are generally three crystal forms of Al2O3, which are a-Al2O3,-b-Al2O3, or g-Al2O3. They all have different structures and different properties. At temperatures over 1300°C, it can be almost entirely converted into a Al2O3.
The high-temperature melt spraying process produces spherical Alumina with high sphericity. This alumina has excellent performance as a filler for rubber, plastics, ceramic raw materials.
The key features of Powdered Spherical al2O3
1. High filling density. This product is capable of filling rubber and plastics with high density.
2. High thermal conductivity. High filling density permits the production of compounds that have a higher thermal conductivity and a higher heat dissipation than crystalline silicon.
3. Low abrasivity:
Its Spherical shape makes it less likely to wear forming machines, dies, and kneading equipment.

Spherical Al2O3 Pulver is used in a variety of applications
1. Spherical Micropowder can be used as a ceramic material. It has excellent pressing properties and sintering capabilities, which are extremely helpful for the production high-quality ceramic products.
2. It can be used as a grinding or polishing material.
3. This is used in the petrochemical and petroleum industries. There are increasing requirements for the pore size distributions and the pore structure of the carrier alumina. You can adjust the particle size configuration to control formed catalyst carrier particles. Distribution and pore size.
4. The thermally-conductive composite spherical aluminum powder has a limited thickening range and good filling performance. It can be used to make new composite materials with high thermal conductivity, such as thermally-conductive gaskets and thermally-conductive silicone grease, thermally-conductive potting (Glue), and thermallyconductive plastics. You can also use it to create artificial teeth or bones.
